American researchers have assembled a small robot that can move like a caterpillar. Engineers
Caterpillar created by scientists can twistclockwise and counterclockwise. With the help of special stabilizers, smooth movement and the return of all track elements to their original shape are ensured.

As the authors of the development note, caterpillars andearthworms, when moving, contract individual parts of their body and use the force of friction to move forward. This way of movement and soft deformable body allow animals to easily move in difficult terrain.
The researchers tested the robot in difficultconditions. For example, he needed to simultaneously rotate his body and continuously move along a circular path. As the researchers note, such adaptive functions will be needed in complex biomedical environments in which a soft system may experience resistance when in contact with tissues and organs in a limited space.
The developers believe that their robot canbe used for endoscopy, biopsy or drug delivery to be released as needed. The engineers demonstrated how their system would store and dispense pills.
